Assertion: Conductors having equal positive charge and volume, must also have same potential.
Reason: Potential depends only on charge and volume of conductor.

Options

A. If both Assertion and Reason are true and Reason is the correct explanation of Assertion.
B. If both Assertion and Reason are true but Reason is not correct explanation of Assertion.
C. If Assertion is true but Reason is false.
D. If both Assertion and Reason are false.

Answer

To solve the question, we need to analyze the assertion and reason given in the problem.

### Step 1: Understanding the Assertion
The assertion states that "Conductors having equal positive charge and volume must also have the same potential."

- **Analysis**: This statement is not necessarily true. While conductors can have the same charge and volume, the potential of a conductor also depends on its shape and the distribution of charge. For example, two conductors with the same charge and volume but different shapes may have different potentials at a given point in space.

### Step 2: Understanding the Reason
The reason states that "Potential depends only on charge and volume of the conductor."

- **Analysis**: This statement is also incorrect. The potential of a conductor is influenced not only by the total charge and volume but also by the geometry of the conductor and how the charge is distributed over its surface. The distance from the point where the potential is measured to the charge distribution plays a crucial role.

### Step 3: Conclusion
Since both the assertion and the reason are incorrect, we can conclude that the correct answer is that both the assertion and the reason are false.

### Final Answer
Both the assertion and the reason are false.
